Find LCM of 684,651,845,598,390 with Prime Factorization


2 684, 651, 845, 598, 390
3 342, 651, 845, 299, 195
5 114, 217, 845, 299, 65
13 114, 217, 169, 299, 13
114, 217, 1, 23, 13

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 5 x 13 x 114 x 217 x 1 x 23 x 13 = 2884698180

LCM Formula to Find Lowest Common Multiple of 684,651,845,598,390

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

684 x 651 x 845 x 598 x 390 = 87752518635600

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

651 : 1, 3, 7, 21, 31, 93, 217, 651

845 : 1, 5, 13, 65, 169, 845

598 : 1, 2, 13, 23, 26, 46, 299, 598

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,651,845,598,390, is 1.

Now, the common factors can be found like this.

684:2x 2x 3x 3x 19

651:3x 7x 31

845:5x 13x 13

598:2x 13x 23

390:2x 3x 5x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 3x 3x 5x 13x 13 = 30420

Therefore, the value for common factors is 30420.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 87752518635600/(1x30420)

LCM = 87752518635600/30420

LCM = 2884698180

Thus, we can understand that the LCM of 684,651,845,598,390 is 2884698180.
